I recommend two sentences:

1: A true warrior dares to face a bleak life and faces the dripping blood; from "For the Memory of Forgetting"

It is most suitable to describe Xu Yunfeng and others;

2: "With a cold brow and a thousand fingers, I bow my head and am willing to be a ox." These are two sentences from a poem by Lu Xun, used to describe these people who sacrificed their lives for the country. Revolutionaries are very suitable.

Please refer to it!
